Musa is a new free jailbreak tweak by iOS developer ToolPod for iOS device owners that want to get more out of listening to music on their iOS devices.

The tweak has three main functions:

To notify you when the music changes via means of a notification banner

To let you use Activator to obtain song details on demand

To give you touch gesture controls for your music on the lock screen

The banner notifications appear automatically whenever your currently playing song finishes and another begins. The notification tells you what the name of the new song is, as well as the artist. You can enable or disable this feature (NowPlaying Options) on demand from the tweak's preferences pane, which is available in the Settings application:

In addition, you can configure banner options, HUD (heads-up display) options, and alert options so that they each have their own Activator action. When you invoke the Activator action that you chose for the HUD, for instance, the HUD will appear and show information about the song that is playing. If you show an alert instead, you will have more options, such as the ability to see lyrics for the song, and the ability to open the Music application. You have the choice of configuring an Activator action for all three, or only some or one of the notification styles.

The last major feature of Musa is the addition of touch gesture controls to the lock screen. You can enable or disable them from the LockScreen Options cell in the preferences pane. The toggles allow you to double-tap on the lock screen to toggle playing music on or off, swipe right on the lock screen to get to the next song, or swipe right on the lock screen to get to the previous song.

The style of the Activator-based song information notifications are made very similarly to those in Launch Notify, a tweak that we showed you last week by the same developer. The two tweaks go well together.

The developer notes that he's working to add lyric functionality to the HUD and banner notification styles, as well as voice notifications to the tweak in the future. If you want to give this already neat jailbreak tweak a try, it's available for free in Cydia's BigBoss repository right now.
